Given:

Percentage of employees in department A

Formula used:

Central angle = 360° × (Percentage of employees in department A)/100%

Calculation:

Central angle = 360° × (Percentage of employees in department A)/100%

⇒ Central angle = 360° × 20%/100%

⇒ Central angle = 360°/5

⇒ Central angle = 72° 

∴ Central angel of the sector representing the number of employees in department A is 72°.
